A User Interface Description Language (UIDL) consists of a specification language that describes various aspects of a user interface under development [1]. Fundamentally, accessibility means that peoples with different disabilities can use a specific product. Particularly, in order to be accessible, a user interface must be perceivable, operable, and understandable for users, including those with disabilities or functional limitations as visual, auditory, physical, speech, cognitive, and neurological disabilities. User interfaces accessibility can be approached through usability. International organization for standardization (ISO) 9241-11 defines usability as the extent to which a product can be used by the specified users to achieve specified goals effectively, efficiency, and with satisfaction in a specified context of use [2]. Accessibility focuses on including people with disabilities as the specified users and a wide range of situations, including assistive technologies, as the specified context of use
